Description
The PLMU11 continuously measures the voltage of each of
the three phases to provide protection for 3-phase motors
and sensitive loads. Its microcontroller senses under and
overvoltage, voltage unbalance, phase loss, and phase
reversal. Protection is provided even when regenerated
voltages are present. Universal voltage operation and standard
base connection allows the PLMU11 to replace hundreds of
competitive part numbers.
Operation
Upon application of power, a 0.6s random start delay begins and
the PLMU11 measures the voltage levels and line frequency
and selects the voltage range. The output relay is energized
and the LED glows green when all voltages are acceptable
and the phase sequence is correct. LED flashes green during
trip delay, glows red when output de-energizes. Undervoltage,
overvoltage, and voltage unbalance must be sensed for
continuous trip delay before the relay de-energizes.
Re-energization is automatic upon fault correction. The output
relay will not energize if a fault condition is sensed as 3-phase
input voltage is applied. The LED alternately flashes red/green
when phase reversal is sensed. Line voltage is selected with
the knob, setting the over and under voltage trip points. Voltage
range is automatically selected by the microcontroller.
